Yeast modifies the nonlinear behavior of the electrode electrolyte interface under high voltage stimulation.

ABSTRACT: In non-linear dielectric spectroscopy of yeast suspensions, previous studies distinguished nonlinear interface behavior from yeast membrane-induced currents by comparing power spectra of solutions with and without yeast. However, this method might be inaccurate because the effect of yeast can not be considered merely an additive contribution. In fact, the presence of yeast on the electrode surface can alter the voltage drop reaching the electrode, thus changing the nonlinear electrode response. No prior research has investigated the effect of yeast presence on the electrode surface using a nonlinear mathematical model. Here, we used a four-electrode system to record responses from solutions when applying a single-frequency voltage of 23 Hz. Using the Butler-Volmer model, we showed that yea
